Scour at Wide Piers and Long Skewed Piers

Author: Sheppard, D Max | Size: 4.30 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 63 | ISBN: 9780309155373

This report presents recommendations for (1) a predictive equation for equilibrium local scour and (2) a potential equation for predicting scour evolution rates at wide piers and skewed piers. These equations provide better estimates of local scour and scour evolution rates than those predicted by currently available equations. Such estimates will reduce over-predictions and the unwarranted need for countermeasures. The material contained in the report should be of immediate interest to state hydraulic engineers and others involved in the design, operation, and maintenance of highway bridges.
